ET3158A

Description générale

The ET3158A advanced load management switches target applications requiring a highly integrated solution. It disconnects loads powered from DC Power Rail (<6V) with stringent off-state current targets and high load capacitances (up to 200uF). Each switch consists of slew-rate controlled low-impedance MOSFET Switch and other integrated analog features. The slew-rate controlled turn-on characteristic prevents inrush-current and the resulting excessive voltage droop on power rails. The ET3158A has True Reverse Current Blocking (TRCB) function blocking unwanted reverse current from OUT to IN during ON/OFF state. These devices have exceptionally low off-state current drain (<1uA max) which facilitate compliance in very low stand-by power applications. The input voltage range operates from 1.5V to 6.0V DC to fulfill a wide range of applications in consumer, optical, medical, storage, portable, and industrial device power management. Switch control is managed by a logic input (Active HIGH) capable of interfacing directly with low voltage control signal/GPIO with no external pull-down resistor required. ET3158A is offered DFN4(1.2×1.6) package, which is ideal for small form factor portable equipment .
